Migration Plugin

Issue #7887

Updated by ttereshc about 4 years ago

It happens only if orphaned content hasn't been fully migrated with the first run. 


 To reproduce: 
  - have orphaned content in pulp 2 
  - run migration, stop it before the content migration is done (ensure that at least one of the orphaned content units was pre-migrated but not migrated.) migrated) 
  - clean orphans in pulp2 
  - run migration again
